ISM in collaboration with the Army Research Laboratory (ARL) is engaged in a multi-year research program focused on rapidly advancing the state-of-the-art in additive manufacturing (AM). Novel fusion-based and solid-state AM technologies are being employed to manufacture next generation materials systems for DoD and Industrial applications. The following AM technologies are currently being established in this program:
- Additive Friction Stir Deposition (AFSD)
- Magnetically Assisted Laser Directed Energy Deposition (MDED)
- Cold Spray Additive Manufacturing (CSAM)
- Aerosol Jetting Multi-Material AM (AJAM)
- Wire Arc Additive Manufacturing (WAAM)
- Smart Solid-State and Fusion-Based AM
A new, state-of-the-art AM research laboratory is currently being developed within ISM that will house several unique AM systems, including those above. The first will be operational in early summer (the remaining systems are anticipated in the fall) and will include a MELD L3 AFSD system, as well as a CSAM system from VRC Metal Systems. Both are solid-state AM technologies, where layer building mechanisms are based on plastic deformation at elevated temperatures, rather than melting and solidification. This leads to highly stable and consistent manufacturing processes, in which unwanted phase transformations and tensile residual stresses can be avoided, and site-specific material properties can be engineered in unique configurations.
For AFSD, these characteristics will be harnessed to develop novel nanostructured and functionally graded materials. For CSAM, our initial research focus is on developing mathematical models which describe the influence of velocity gradients within the supersonic flow field on the resulting material properties and defect generation.
ISM researchers are utilizing these new technologies to push the boundaries of innovation and help establish UK as a world leader in advanced AM.
